Core Features

Premium material & dual heat treatment

Made of CR-V (6150) chrome-vanadium steel.
The character head reaches HRC 58–62 for lasting, clear marks; the striking end is tempered to HRC 38–46 to absorb impact and prevent cracking.

High-precision design

A double-bevel design makes visual alignment and precise striking easy.

Quick identification

Font and size are marked on the side of the stamp for fast identification during work.

Thoughtful craftsmanship

The surface is sandblasted for a better anti-slip grip and greater durability.

Exclusive Patent · Multi-Function Storage Box

More than storage — a core accessory that boosts working efficiency and safety:

Patented in Taiwan, USA, France, Germany, China, Vietnam and more — an original design.

All-round hand protection

Strike with the stamp held in the box — your hands stay clear of the hammer for a safer, steadier hit.

Precise level alignment

The box keeps the tool perfectly flush with the workpiece — a straight strike and consistent depth, every time.

Viewing-window positioning

A built-in viewing window makes positioning easy and keeps impressions from skewing.

360° no directional limit

Rotate the box freely to suit the way you work.

Quick-access design

Patented PP box with a three-hole lid for fast, safe daily access.
